A Primer of 
Home Lighting 


This book points out inci- 
dents that happen in the 
home, perhaps your home, 
as aresult of improper light- 
ing—and the manner in 
which they may be corrected. 
It helps you select the right 
lamps for your lighting fix- 
tures. 


There’s a right lamp for every fixture.

OT hosRicwaleniee aad Tas of Fite Placéd 
Properly, will Eliminate the Shadow 
Shadows of this kind are the result of a cen- 


tral fixture which throws undiffused light 
directly on an object. 


Frosted or White MAZDA lamps will help get 
rid of such shadows, but to entirely eliminate 
them the light should come from some fixture 
such as a piano lamp directly over the music; 
a stand lamp placed to the right or left of the 
piano; or a central semi-indirect fixture —which 
throws most of its light on the ceiling, diffusing 
the light throughout the entire room. 


The cost of good lighting is quite small when 
compared to the comfort and convenience it gives. 
Proper lighting costs no more than cream for the 
morning coffee. Your monthly bill for lighting 
will generally be less than the amount you spend 
for butter in the same length of time. Good light- 
ing is not an extravagance.

Shadows like these are caused by undiffused 
light from either ceiling fixtures, side or wall 
brackets, table or floor lamps. 


The right frosted or White MAZDA lamps 
help eliminate these shadows because they 
diffuse the light. 


Another method of obtaining good diffused 
light is by the use of an efficient, clear MAZDA C 
lamp in a central semi-indirect fixture. 


The number of sockets in a fixture indicates the 
number of lamps which should be used. If there 
are four sockets, each socket taking a 25-watt lamp, 
and you use a 75- or 100-watt lampin only one socket 
the fixture not only appears unbalanced but in 
most cases produces glare. : 


Guests notice your lighting even before they do 
draperies and furnishings.

There are two reasons why closets are gener- 
ally dark. First, because no lights are provided 
in the closet; secondly, because in most rooms 
the undiffused light from the central fixture 
causes one’s own shadow to fall directly in 
the closet. 


A fixture such as shown above with a MAZDA 
C lamp will help, but the best way is to put a 
lamp in the closet. It costs but little. 


Many homes have only one fixture per room. 
Think how uninviting a room with only one window 
would be. While it may be impractical tocut extra 
windows where they are wanted, itis always possible 
to install extra lighting fixtures—as many of them 


as you need—and where you want them,—and at a 
small cost.

The Right Lamps and Type of Fixtures Placed 
Properly, will Eliminate the Shadow 


When the light comes from a low central 
fixture, there will always be a shadow on the 
work unless that work is carried on directly 
under the fixture. 


The remedy is to use a MAZDA C lamp in a 
fixture close to the ceiling or to drop a light 
directly over the work. 


An extra socket—an extra outlet, means very 
little added cost, yet means so much in added 
convenience, the saving of time, and the assurance 
of safety. 


Putting light where you want it and where you 
need it costs, in many cases, no more than the price 
of a good pair of shoes. And yet its convenience 
lasts for years.

The Right Lamps and Type of Fixtures, Placed 
Properly, will Eliminate the Shadow 


The only way to light both sides of an object 
is to have light on both sides. 


Many bathrooms have a single fixture hung 
in the middle of the room or one fixture on 
one side of the mirror. If the bathroom is 
white, a frosted or White MAZDA lamp in 
these fixtures will help get rid of shadows. 
Another help is to raise the fixture close to the 
ceiling. But, to entirely eliminate shadows 
use two fixtures, one on either side of the mirror. 
This applies wherever a mirror is used, whether 
in bathroom, bedroom or hall. : 


Good lighting is inexpensive. In comparison to 
furnishings such as a piano, rugs, tables, draperies, 
it costs very little; yet the enjoyment of the piano 
may be spoiled by improper lighting; the effect of 
well selected draperies, paper and rugs ruined by 
the wrong method of illumination, while furniture 
may lose half its charm under the glare of im- 
proper light.

The Right Lamps and Type of Hines Placed 
Properly, make Vision Easy at Night 


On account of insufficient light, many women 
are unable to do needlework at night. 


Yet it is always possible with the right 
lamp and fixture to obtain more than enough 
light for the finest kind of work. Use either a 
table or stand fixture, making sure you have 
the correct size oflamp. A semi-indirect fixture, 
with the proper clear MAZDA C lamp, will give 
plenty of light for work anywhere in the 
room. 


There is no need for changing your habits of 
living when night comes. You should be able to 
do fine sewing, crocheting, or read fine print just 
as easily in the evening as at noon—and this without 
moving your chair or changing the arrangement of 
the room.

‘Use the Right Frosted or White Mazda Lamps 
Whenever the Lamps Themselves are Visible 


Glare is caused either by lights that are not 
properly shaded or by light that is not suffi- 
ciently diffused. 


To avoid glare use either a frosted or White 
MAZDA lamp, or place the proper silk or glass 
shade around a clear lamp. 


Fixtures having no shade usually employ 
round bulb MAZDA B lamps. These lamps 
should be all frosted. 


If a light in your home makes you feel a tendency 
to squint or shade your eyes you may know that 
glare is present. 


Make this test for glare. Look at any of your 
lighting fixtures steadily for ten seconds—then 
close your eyes. If you can still see the image of the 
light, you may be sure that glare is present.

Ts there glaring light in your eyes? 














Use the Right Frosted or White Mazda Lamp 
Wherever you look directly into a light 


Dining room domes improperly designed, or 
hung too high, are frequently the cause of 
bothersome glare. 


With such domes, the use of the right frosted 
or White MAZDA lamp will minimize this glare. 
A clear lamp should never be permitted. To 
eliminate glare entirely the light should come 
from a dome hung approximately 26 inches 
above the table. 


When outlets cost so little it is not necessary 
to inconvenience oneself by attempting to put the 
connecting plug of an appliance in a lamp socket. 
It is not only inconvenient and troublesome but 
is unsightly and generally means that improper 
lighting will result. 


There should be at least one convenience outlet 
in every room.

Properly, make the Cellar Safer 


Many cellars, store rooms, etc., are unin- 


viting, dirty and unsafe asa result of insuf- 
ficient light. 


The right light will literally transform such 
places. Use a white MAZDA lamp with a re- 
flector for the furnace, and for the laundry. 


For the fruit closet, no reflector is needed on 
the lamp. 


A well lighted cellar makes possible the use 
of a work bench. 


Lamps get just as dusty as furniture. 


A month’s dust on lamps and fixtures may absorb 
25 per cent of the light. You are then paying for 
current you are not using. 


Be sure to clean your lighting fixtures once a 
month. 








So earenidenends on the lighting! 





How to Select 
the Right Lamp for Your Lighting Fixture 


On the following pages are lighting fixtures similar 
to those you havein your home. Pick out the fixture in 
question and then notice the kind and size of lamp 
which should be used with it. 


Fixtures in different rooms may require different 
sizes of lamps. The lighting experts who prepared these 
pages have taken a small room as one, 9 by 12 feet or less; 
a medium room about 12 by 15 feet; a large room 15 by 20 
feet or more. 


Example: Suppose you have a fixture like that 
shown in the upper right-hand corner of page twenty- 
three. If your room is classed as a small room you know 
that a 25-watt frosted lamp is the lamp to use in this fix- 
ture. If theroom, however, isa medium one, look through 
the following pages until you find the fixture shown again, 
which in this case is on page twenty-four. Thus, for 
this type of fixture in a medium room a 40-watt MAZDA B 
lamp should be used. 


These pages have been prepared assuming that the 
room is a moderately light one. If the rugs, draperies and 
wall paper are quite dark in color, a larger lamp may be 
necessary. 


Many of the fixtures shown, although widely used, 
are not of the most effective type, or the style which 
would be recommended when building a new home or 
installing new fixtures. We will be glad to demonstrate 
the more recent designs at any time.

What to do When a Fuse Blows Out 


If you are operating an electrical appliance and the appliance 
refuses to work, first find out whether or not your lamps will light. If 
the lights turn on make sure that the connections are fast at both ends 
of the cord. 


If these are all right, the trouble probably lies in a broken wire in 
the connecting cord. The cord can be repaired or a new cord furnished 
by your Central Station or electrical store. 


If the lamps do not light: 


Immediately disconnect the cord of the appliance from the socket 
to which it is attached. Now try the lamps in other rooms in the house. 
If none of these will light, either the current has been turned off by 
the Central Station or the fuses in the main switchbox have blown out. 


If you find that some of the lamps in the house light, one of the fuses 
in the distributing panel and not one of the main fuses has blown. 


The main fuse with the switch is always located near the meter, 
either in the cellar or in the attic. The distributing panel may or may 
not be near the meter. 


Note: In some houses there is no distributing panel. In this case 
the two fuses at the main switchbox control the whole lighting circuit. 


If the main fuse has blown, open the switchbox and take out one 
of the fuse plugs. Before placing in a new fuse screw in a spare lamp. If 
it does not light, or if it burns at half brilliancy, 
everything is O.K. and the new fuse may be inserted. 
If the lamp burns at full brilliancy, there is a short 
circuit somewhere on the line. In this case call for a 
Central Station representative or your electrician. 


However, with a new fuse, 
if your lamps still do not light, 
it is the other fuse at the main 
switchbox which has_ been 
burned out. Take this out, test 
with lamp as before and put in 
a new fuse, which in this case 
would be the fuse you first took 

Distributing panel out. Where a fuse has blown in Main switch box 

the distributing panel turn on 
all the lamps that will light in your house (that is, if you do not know 
which fuses control which rooms in your house), start in at the top of the 





panel and unscrew the fuses in order until you find one that does not 
turn out some of the lights when the fuse is unscrewed. Now try out 
this set of fuses as you tested the main fuses, using the spare lamp. 


Note: In some houses the distributing panel has a metal front 
behind which the fuses are located. There are switches in the panel. 
In this case, start as before and turn the switches off in order until one 
switch, when turned off, does not turn out any lights in the house. 
Now, open the door plate covering the fuses and test the two fuses 
connected with this switch. 


Note: In many houses the fuses are of the cartridge type. To test 
with a lamp here, you will need a socket with two short wires attached. 
Touch these wires to the two sides of your fuse clips. Your electrician 
will make up such a testing device for you at small expense. 


Do not replace your appliance 
until it and the connecting cord have 
been tested out by your electrical 
store or Central Station. Cartridge fuse

How to Order Edison MAZDA Lamps 


When ordering lamps be sure to get MAzDa lamps. Mazpa is the 
trade-mark which stands for the highest standards in lamp manufac- 
ture. Only those companies making lamps up to the MaAzDa standard 
are permitted to use this trade-mark on their lamps. 


Ask for lamps by name, giving the size, kind, and voltage. Thus 
‘Five 40-watt, all frosted, 110-volt, Edison MAzpDa B lamps.”’ 


If you merely ask for lamps you may or may not get MaAzpDa lamps. 


The correct voltage is important. Lamps of too high a 
voltage burn dimly. Lamps of too low a voltage burn out too 
quickly. If you come to us you can be assured of lamps of 
the correct voltage.
